A huge mahalo to all the game developers, analysts, and assorted experts I spoke to for this book—thanks for bringing your particular wisdom to the proceedings. Extra thanks to Billy Pidgeon, analyst with M2 Research (www.m2research.com) for doing double duty as both an interview subject and this book’s technical editor. Thanks just as profusely to all the folks supporting this book at Wiley, especially Ms. Mary James, the editor who first gave me the call. Also, much gratitude to Jennifer Lynn of Page One Editing and copy editor Kezia Endsley, for helping make this book coherent and whole. Cheers always to David Fugate of Launch Books (www.launchbooks.com), my agent of six years, for his unflagging support where it matters most.
